What to do if my Immergas Water Heater has an ignition block?
To resolve an ignition block in your Immergas Water Heater, press the Reset button. However, if this issue occurs frequently, it is recommended to contact a qualified technician for assistance.
What to do if my Immergas Water Heater shows an overtemperature thermostat block?
If your Immergas Water Heater displays an overtemperature block, allow the system to cool down first. Then, press the Reset key to clear the block. If this issue happens often, contact a qualified technician for help.
Why Immergas Water Heater fails due to flue gas pressure switch failure?
Flue gas pressure switch failure in your Immergas Water Heater can occur if the intake or exhaust pipes are blocked, due to a fan fault, or a fault on the flue gas pressure switch. If normal conditions are restored, the water heater restarts without needing a reset. If the issue persists, contact a qualified technician.
What to do if my Immergas Water Heater maximum number of resets?
To eliminate the anomaly on your Immergas Water Heater, press the Reset button. Note that the anomaly can be reset 5 times consecutively, after which the reset function is disabled for at least one hour.
What causes low power supply voltage in Immergas Water Heater?
Low power supply voltage in your Immergas Water Heater happens when the power supply voltage is lower than the allowed limits for the correct functioning of the water heater. If normal power conditions return, the water heater will restart without needing a reset. If this happens frequently, contact a qualified technician.
What causes parasite flame in Immergas Water Heater?
A parasite flame in your Immergas Water Heater can be caused by a leak in the detection circuit or an anomaly in the flame control unit. Try resetting the water heater. If the problem continues, contact a qualified technician.
What to do if my Immergas Water Heater push button control panel anomaly?
If your Immergas Water Heater experiences a push button control panel anomaly, the water heater restarts without needing a reset when normal conditions are restored. If this issue continues, contact a qualified technician.
The device described in this manual is a gas-fired water heater, specifically the "CAESAR 14 3 E" and "Super CAESAR 17 3 E" models, manufactured by Immergas. Its primary function is to produce domestic hot water. The appliance is designed for wall installation and is suitable for use in various environments, including outdoors in partially protected areas or indoors, depending on the specific configuration.
The water heater operates by heating water to below boiling temperature at atmospheric pressure. It can be connected to a DHW (Domestic Hot Water) distribution network. The appliance features a sealed combustion chamber and is fan-assisted, ensuring efficient air intake and flue gas exhaust. It is designed to operate with both methane gas (G20) and LPG (Liquefied Petroleum Gas), with conversion kits available for switching between gas types.
The control panel allows users to manage the water heater's operation. It includes an On/Stand-by/Off button, a Reset button, and a temperature selector. Users can regulate the DHW temperature according to their needs. The display shows the current water temperature, flame presence, and output efficiency. The water heater automatically ignites when there is a demand for hot water. If ignition does not occur within 10 seconds, it enters an "ignition block" state, indicated by an error code.
The device incorporates several safety features. An overtemperature thermostat prevents excessive internal overheating. A flue pressure switch monitors the intake and exhaust pipes, detecting blockages or fan faults. The appliance also includes an anti-freeze protection system, which, when properly installed with an optional kit, protects the water heater down to -15°C, provided it remains connected to the electricity supply and the anti-freeze components are functional.
The water heater is equipped with an "Information menu" that allows users to view various functioning parameters such as instant DHW flow rate, inlet and outlet water temperatures, and the set temperature. It also features a "Solar function" which is always active, allowing the water heater to receive pre-heated water from solar panel systems. In this scenario, the water heater will not switch on if the inlet water temperature is already at or above the set value. A "Solar panels coupling function" is available, requiring a mixing valve upstream to ensure optimal performance when integrated with solar systems.
An automatic slow ignition function with timed ramp delivery ensures a smooth ignition phase. The burner ignites at a pre-set ignition power value and then gradually increases the gas supply based on DHW withdrawal, preventing abrupt changes and ensuring consistent operation.
To use the water heater, users must ensure the DHW inlet valve is open and the gas cock upstream is open. The appliance is turned on by pressing the On/Stand-by/Off button until the display activates. The DHW temperature can then be adjusted using the temperature selector. The display provides real-time information on the water heater's status.
The water heater can be set to "Stand-by" mode, where it remains powered but inactive, or completely "Off," where it is still live but no functions are active. For prolonged periods of non-use, it is recommended to disconnect the external omnipolar switch and close the gas cock.
In case of anomalies, the water heater signals them by flashing error codes on the display, which are listed in the manual for troubleshooting. Common issues include ignition block, overtemperature thermostat block, domestic hot water probe anomalies, flue gas pressure switch failure, parasite flame, control panel anomalies, and low power supply voltage. Many of these can be reset using the Reset button, but persistent issues require professional assistance.
The appliance is designed for compatibility with Immergas flue systems, which are essential for proper operation. Different installation configurations (Type B for open chamber and forced draught, Type C for sealed chamber) are supported, each with specific requirements for air intake and flue gas exhaust. The manual provides detailed instructions for installing various kits, including horizontal intake-exhaust kits, vertical kits with aluminum tiles, and separator kits, to adapt to different installation scenarios.
Regular maintenance is crucial for ensuring the water heater's optimal safety, performance, and operational characteristics over time. The manual recommends yearly servicing by professionally qualified heating/plumbing technicians.
Key maintenance tasks include:
The manufacturer emphasizes that installation and maintenance must comply with current regulations and manufacturer instructions, and only professionally qualified staff should perform these tasks to ensure safety and validate the warranty.
